I think the word I would use to describe this film is "beautiful". The artwork blew me away, it is absolutely amazing, so sharp and detailed but soft and almost dreamlike, with the sky constantly through the film being filled with stars and heaven knows what else! The soundtrack is also very fitting and really nice, although not entirely sure how much I love the final pop song. As for the storyline, I liked it, I am a fan of romantic films, and sad ones as well but it wasn't my favourite, I think it was perhaps a little too short, left a little bit too much unexplained. But then maybe that was its point. I agree with another of the reviewers that "The girl who leapt through time" and "millennium actress" are both arguably better films but I certainly don't think this film was far off the mark.
To conclude, this film is gorgeous, the artwork and soundtrack make the film stand out from the rest and whilst the storyline and composition may not make this the best film, it certainly makes it one not worth missing!
